"Goodbye, Baimo."

Bai Mo narrowed his eyes and stared at Kaname Madoka's back.

Based on the existing information, with Kaname Madoka's intervention, I should actually do nothing, and Witch Night will be led by her and Homura Akemi.

You can just play a supporting role, or just stand by and cheer for others to do their best like Kyubey, and act as a spectator.

However, it is really hard to feel at ease to base all the future on Kaname Madoka's personal thoughts.

“Maybe this is the person.”

Bai Mo looked at the almost disappearing figure and whispered, "God will obviously solve the Witch Night. God will solve all problems, but people... want more. They want sick and twisted peace of mind."

Clapping his hands, Bai Mo casually produced a chair, sat down, supported his chin with both hands, and his eyes were solemn.

Countless clues appeared in my mind: Kaname Madoka, Homura Akemi, Madoka, Flame Demon, Incubator, Kyubey, Soul Energy, me, Soul Gem, Reality Distortion, Unknown Variables...

One puzzle piece after another represents the corresponding related information, as if these elements have explained the whole picture of this "world" and described how the universe was formed.

"Homura Akemi's magic is about time and reincarnation, which is equivalent to performing some incomprehensible operations on the timeline.

If I think of myself as a character in a novel, then she can jump around the plot at will. Now she is communicating with me on this page, and perhaps at the same time she can "re-" communicate with me on the previous page and change the status quo of this page. "

"It's very troublesome. From this, it can be confirmed that I can't use the current time as a reference, but the gray fog space... may be able to serve as a reference system for time."

Bai Mo tapped the armrest with his fingers, turned his head to look at Kyubey, and asked, "What exactly is time?"

What exactly is Homura Akemi's time, and how can the present time be described?

Chubby wagged his tail and replied, "According to human understanding of time, time is a very abstract word."

"Really? Then what exactly is time?"

"Time, according to human civilization's understanding of time, time is this." Qiubi jumped off Baimo's shoulder and tapped the ground lightly.

The next moment, the world around him turned upside down, and this place became a classroom. Kyubey was floating in front of Bai Mo, as if he had become a teacher teaching a class.

“At the beginning of time, it was believed that everything was created by God. This is a philosophical question: where do I come from and where am I going?”

"The answer, which is a combination of multiple perspectives, is affected by various factors."

"This is an incomplete view. Although the universe may have been created by Yuan Shen and Yan Mo, this view of human beings on time is ultimately an incomplete understanding."

There are no ideas with preconditions, no theories to support them, and only the imperfect logic of the individual civilizations, which makes it impossible to make accurate judgments.

Cupid waved his claws, and many discussions of philosophers flashed before Baimo's eyes. Various theologians all believed that time came from God.

God created the universe, and then time came into being.

God created the world in seven days.

The original space and time of major civilizations were created by God.

"Isaac Newton believed that there is absolute time and absolute space in the universe. Absolute time is real and flows evenly at its own rate, independent of any external things. In addition, there is also relative time, which is a relative change of time."

"But both of these are based on personal subjective views." Bai Mo keenly saw the flaw in it.

What these two express is just like what Confucius said - Time flies like an arrow, never ceasing day or night.

Time is like a river, vast and mighty, constantly moving forward.

However, this is just a subjective view, just like seeing the sun rise in the east and set in the west, and then thinking that all this is the inevitable eternal law of truth, the sun is destined to rise and set. In essence, this is just a concept that comes from the active contact of things with human visual senses, which is one-sided and thin.

What the internal laws and essence are are not separated from sensory contact, and the core is described in an abstract way.

“Time slows down for moving objects. Time and space are a whole, an inseparable union.”

Curved space-time is the essence of gravity.

Baimo held his chin with his hand, and the rules and laws formulas written down by the ancient sages emerged before his eyes.

From the macroscopic to the microscopic, the scale of time seems to be related to the bubble of quantum tide, but it seems so counterintuitive, even in direct conflict with common sense.

In terms of the perception of time, when time goes too fast, it seems that we can travel through time to the future.

The space-time view of relativity theory - space-time is one, continuous, smooth and scalable, time expansion, space-time curvature...

Quantum space-time view - space-time coupling, resonance with energy, not smooth...

Quantum Gravity Theory - The unit of time T is not important...

Quantum entanglement - instantaneous influence, ignoring time and space...

Through many explorations, we have pieced together the basic concept of time.

“Time is affected by the movement and interaction of the smallest microscopic particles, and a three-dimensional multi-dimensional time-domain axis spectrum emerges.”

Kyubey calmly expressed his understanding of this next level.

"In the worldview recognized by human civilization, this is the next level of space-time concept, that is, a single fixed description of "time" does not really exist."

"Due to the limitations of individual thinking and cognitive perspective, a single human individual cannot accurately understand the concept of time and can only define time through abstract language descriptions."

Bai Mo snapped his index finger, materialized a pen and paper in front of him, and began to continue explaining the concepts that Kyubey had been talking about.

It comes from the understanding of time by the top civilization in the universe. Even if it is restricted by Bai Mo's own personal worldview, it is an immeasurable treasure.

…………Time passed quickly, and when Kyubey finished everything, the paper in Bai Mo's hand became a thick book.

“There is still a lot to learn.”

Bai Mo said with emotion.

What Qibi narrated was extremely easy to understand, and in a sense could be considered to be tailor-made for Bai Mo's "level" of "life".

But even so, the differences in all aspects are huge.

The difference between ordinary people on Earth and the top civilization that studies the entropy of the underlying structure of the closed universe is many times greater than the gap between cells and humans.

Of course, the same is true of the distance between Kyubey and Madoka.

Relatively speaking, there is no difference between Baimo and Qiubi to Yuanshen.

"The road ahead is long and arduous, but I will search for it up and down." Bai Mo took out a pen and wrote on the cover of the book, then stuffed it into Cupid's mouth, letting it serve as a temporary backpack.

Bai Mo rubbed his wrist, put down the chair, turned around and walked towards home.

As he walked, he wrote and drew these basic laws and theorems in his mind, using mathematics as a tool to try to understand and digest the contents in a human way. (End of this chapter)
